This file is 2 x 2.4 meters at 180 dpi. Since I cannot get that out of my printer, I change it to 1 X 1.2 meters at 360 dpi. For postcards (50 x 55 cm), I change to 720 dpi; for really small, to 1440 dpi. In each case, there is no loss of pixel-level detail but rather a noticeable detail enhancement. Again, I have had enough input over the last years to confirm that my pot-smoking habit has not consumed my perceptive abilities.

Hi Laurence,

This looks like a print you sent me a few years ago. I thought it was a number of images stitched together...?

Anyway, no matter how close you get to it, you simply can't see any artifacts at all. It is a 'Zero Viewing Distance' print.
